Clear the corner decisively and counter. Attack the ball rather than waiting for it, clear it high and away from goal, win the second ball, and exploit the space behind the committed attackers with a fast break.
Serve an inswinging corner into the box. A defender attacks the ball and heads it clear, high, far and wide, never letting it bounce. A midfielder reads the second ball and wins it at the edge, then plays a long ball to a striker who has stayed up, breaking into the space the attacking team vacated. Set marking assignments (zonal or man), a near-post defender, and a keeper who commands the box, then rehearse the clear-and-counter.
Fork it into your private drills, then change the animation, adjust positions, swap equipment, or drop it into a session block.
